Abstract (en)

[origin: WO2020122865A1] A method for manufacturing a structural component of a blade segment for a segmented rotor blade of a wind turbine (10) includes providing a mold (150) of the structural component. The mold (150) has an outer wall (156) that defines an outer surface of the structural component. The method also includes securing at least one tooling pin (162) to the outer wall (156) for defining a pin joint slot (50) in the structural component. Further, the method includes laying up one or more outer fiber layers (168) in the mold (150) so as to at least partially cover the outer wall (156). The outer fiber layer(s) (168) has at least one hole (169) that receives the tooling pin(s) (162). As such, the outer fiber layer(s) (168) form the outer surface of the structural component. Moreover, the method includes placing one or more structural features (170) atop the outer fiber layer(s) (168) in the mold (150). In addition, the method includes infusing the outer fiber layer(s) (168) and the structural feature(s) (170) together via a resin material so as to form the structural component.
